Effect of Host Availability and Egg Load in Trichogramma platneri Nagarkatti (Hymenoptera: Trichogrammatidae) and Its Consequences on Progeny Quality
Experiments were conducted to determine whether Trichogramma platneri Nagarkatti manifested a somatic-gametic trade-off and whether it was affected by host availability and host size. Large wasps produced on Trichoplusia ni Hübner and limited to five or 15 T. ni eggs daily, produced a similar number of progeny as wasps offered hosts from emergence. Similar results were obtained when they were d...
متن کاملInnate and Learned Olfactory Responses in a Wild Population of the Egg Parasitoid Trichogramma (Hymenoptera: Trichogrammatidae)
Parasitoid insects face the fundamental problem of finding a suitable host in environments filled with competing stimuli. Many are deft sensors of olfactory cues emitted by other insects and the plants they live on, and use these cues to find hosts. Using olfactory cues from host-plants is effective because plants release volatile organic compounds (VOCs), in response to herbivory or ovipositio...
متن کاملDevelopment of endosulfan tolerant strain of an egg parasitoid Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae).
A strain of T. chilonis, an egg parasitoid of lepidopteran pests tolerant to the most commonly used cyclodiene insecticide--endosulfan was developed in the laboratory. Tolerance to endosulfan was induced by exposing adult parasitoids sequentially from a sub-lethal concentration (0.004%) to the field recommended concentration (0.09%). The strain acquired tolerance to the insecticide after 341 ge...
متن کاملSide-Effect of Certain Herbicides on Egg Parasitoid Trichogramma evanescens (West.) (Hymenoptera: Trichogrammatidae)
Three laboratory experiments were conducted to evaluate the side-effects of four common herbicides used to control weeds associated with local crops on egg of the parasitoid Trichogramma evanescens. These herbicides are Glyphosate 48%SL, Bromoxynil 24%EC, Thiobencarb 50% and Clodinafop-propargyl 15%WP. The biological aspects such% parasitism, % adult emergence, sex ratio, developmental period a...
متن کاملHost-foraging success of three species of Trichogramma (Hymenoptera: Trichogrammatidae) in a simulated retail environment.
Three species of trichogrammatid egg parasitoids (Trichogramma deion Pinto & Oatman, Trichogramma ostriniae Pang & Chen, and Trichogramma pretiosum Riley) (Hymenoptera: Trichogrammatidae) were evaluated under laboratory conditions as potential biological control agents for the Indianmeal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), on retail shelves. A single shelving unit was...
